Description

Trigger pump nozzle

This creation is about a trigger-type pump nozzle that can be operated with one hand and that greatly extends the life of the nozzle.

Press, the conventional air pump nozzle is as shown in China's Announcement No. M318073. The wind nozzle is tied into an assembly hole, and the rubber nozzle, the clamp seat, the elastic element and the pressure injection are arranged in the order from bottom to top. Further, a wrench with a cam is pivoted above the injector. When inflating, we only need to insert the American/French nozzle from the bottom into the tuyere, and then drive the wrench to make the cam force the pressure. The injector overcomes the predetermined elastic force of the elastic element and moves down along the axial direction of the assembly hole, and further suppresses the "axial elastic deformation" of the air nozzle, so that the air nozzle can be "radially elastically deformed" and the airtight clamping US/French connection The mouth is used for subsequent inflation. After the inflation is completed, the person must reversely drive the wrench to release the injector, so that the tuyere returns to its original shape to release the US/French nozzle.
However, the conventional configuration still has the following problems in practical use:
1. When we want to inflate and drive the wrench, its force must not only overcome the elastic components, but also the "axial elastic deformation" and "radial elastic deformation" of the air nozzle, which is quite laborious and difficult to operate with one hand. It is necessary to hold the wind mouth and the other hand to drive the wrench in one hand, which is enough for the inconvenience. Especially when the ball is inflated, the ball must be clamped through the feet to operate the pump. Gas nozzles often have a sense of rush.
Second, the rubber tuyere is to clamp the American/French joint by converting the vertical "axial elastic deformation" into a horizontal "radial elastic deformation". The wind nozzle itself is subjected to great stress and is extremely elastic and fatigued. The loss of air tightness causes us to have a problem of air leakage from time to time when inflating.
This creator has developed the creation by considering the shortcomings of the inflator nozzle, the inability to operate with one hand and the inability to use the airtight grip.

The present invention provides a trigger-type pump nozzle that includes at least:
a wind mouth head has a handle portion on the outer circumference thereof, and a push-out hole whose aperture is gradually diverged and penetrates through the bottom end, and the push-out hole has a notch opposite to the handle portion, and the top end of the push-pull hole is coaxially connected There is a first hole, and the first hole is further connected to an air inlet;
a tuyere having a mouth for gripping the mouthpiece, wherein the tuyer is positioned at an origin position in the push-out hole through a limiting member, and has a margin that can be moved up;
An injector, which is slidable along the first hole, has an intermediate hole that is connected to the air inlet, and is pushed by an elastic member to abut the top end of the air nozzle, and the nozzle is inserted upward to insert the nozzle hole to drive the air nozzle When moving up, the push hole can be clamped to the mouth by pressing the mouth hole, and the intermediate hole is just connected to the mouth; and a trigger arrangement is mainly configured by coupling a brake member to the wind nozzle head to make the brake piece One end edge can provide finger manipulation of the grip handle so as to interlock the other end edge of the brake member into and out of the push hole through the notch to control whether the tuyere is positioned at the position of the clamp nozzle.
Therefore, this creation only needs to drive the handle of the wind mouth with one hand, that is, the mouth of the American/French mouth can be inserted into the mouth of the wind mouth to facilitate inflation, and more importantly, the finger can be grasped by the hand. The brakes are interlocked to further secure the push-out holes to tighten the American/French nozzles. In addition, the creation of the air nozzles is mainly to force the American/French nozzles by the horizontal force applied by the push holes, thus greatly reducing the wind. The mouth is required for elastic deformation, which in turn effectively extends the service life of the tuyer.
